Initially, I used the Soma Ayurvedic Vitamin C Serum - Citrus and Rose ($118)only in my morning routine, but it felt so luxurious and nourishing on the skin, I had to incorporate it into my nightly routine as well. I use around two to three drops for my face and bring the remaining product down my neck. I gently pat the serum into my skin and even hold it near my nose for a relaxing, sensorial experience. To get the product absorbed into my skin, and to enjoy the experience, even more, I use one to two more drops of the oil and give myself a serene facial massage. Since the serum has an oil base, I noticed that it instantly gave my skin a radiant glowy appearance. I noticed an overall change after two weeks of consistent use. My skin was brighter, more even-toned, and a few of my dark spots looked lighter. My skin felt healthier, balanced, and I wasn't getting any reactive breakouts as well!
